I am thinking about running twins on my truck. Right now I am using an Aurora 2000 and I was wondering what would be a good turbo to use for twins.
Turbo choice for twins
- Thread starter LilJ393
- Start date
it would pending a few things is some ones kit going to fit it ? and i would say it should be wastgated ? and what are your goals with the truck ? for a racing aplication it would be a bit small unless it had a decent size wastgate . for a towing or street truck it would do fine its not much biger than a stock turbo . call nathan at mpi he will know if he has a set that would work with your a2k , if your building yourself than it would be the same as any other turbo just get the apripriate size pipes flanges ect .
edit to answer you original question a s475 would be a good mate for your a2k .

Yeah I woild be building it myself. it is used for towing and a little street racing and ocasional drag racing. i just wanted to find something that would not be to big i do not have and studs or anything like that
is the a2k wastegated ? and othergirl just posted a s475 for sale that would be a good mate for your turbo . i think it was only 550 shipped ? polished cover and everthing
as far as being to big you can build waste gates into the system for both chargers to regulate how hard the chargers are pushed for boost .

you will have to find out it will have to be gated some how to work well ? i have heard there are pedistall spacers that are gated might be a option i have never looked into external gates for the small turbo , i know there is a gated t4 pedistall that just came out but it might be cheaper to sell your turbo and get a different model ?

not nec on the big one depending on the total boost if total boost was too high gating the big one can lower it , but i would for shure make shure the little is gated if not drive pressure tends to be a issue and you run the risk of overspeeding it . if the total boost on a twin setup is around 45 psi you would want the little one suplying aroung 20-22 , and the big one to be aroung the same if anything you want to make shure the big one is suplying more boost tyhan the little one , wastgates are the only way to control this unless the chargers are matched perfectly .
that suprising how can that be called a upgraded turbo ? i was wondering why it's not on there site any more
